THE ECONOMICS OF NON-GMO SEGREGATION AND IDENTITY PRESERVATION

We survey grain and soybean handlers and producers in the U.S. and EU to estimate costs of preserving the identities of GMO and non-GMO crops in marketing channels. We introduce our estimates into the IFPRI IMPACT model to simulate the effects of identity preservation on farm incomes and consumer well-being.Research and Development/Tech Change/Emerging Technologies,

Characterization of cells of amniotic fluids by immunological identification of intermediate-sized filaments: Presence of cells of different tissue origin

Antibodies against intermediate-sized filaments, of the prekeratin or vimentin type, were used to investigate the presence of these filaments by indirect immunofluorescence microscopy in cultured and non-cultured amniotic fluid cells, in frozen sections of the placenta and in isolated cells of the amniotic epithelium. Two major classes of cells can be cultured from amniotic fluids, namely cells of epithelial origin containing filaments of the prekeratin type and cells of different origin which contain filaments of the vimentin type but are negative when tested with antibodies to epidermal prekeratin. The presence of prekeratin type filaments correlates with the morphology of colonies of amniotic fluid cell cultures in vitro as classified by Hoehn et al. (1974). Cells of E-type colonies are shown to be of epithelial origin. In contrast our data indicate a different origin of almost all cells of F-type colonies and of the large majority of cells of AF-type colonies. Cells of epithelial origin and positively stained with antibodies to epidermal prekeratin are occasionally scattered in F-type colonies and in variable percentages (up to 30%) in AF-type colonies. Surprisingly, cryostat sections of the amniotic epithelium and isolated groups of amniotic cells showed positive reactions with both antibodies to vimentin and prekeratin. The possibility that amniotic cells may be different from other epithelial cells in that they contain both types of filaments simultaneously already in situ is presently under investigation

A submerged Late Cretaceous podocarpaceous forest, west coast, South Africa

During mini-submersible dives in De Beers offshore concessions on the middle shelf of Namaqualand, on the west coast of South Africa, a fossil forest was located and sampled. Over an area of 2 km2 there are numerous in situ and prostrate trunks on a gentle slope, 136-140 m below sea level and about 32 km offshore. Micro-palaeontological dating shows that the sediments are of Coniacian age. The silicified woods have been identified as members of the Podocarpaceae and one new species is described, Podocarpoxylon jago Bamford & Stevenson sp. nov. The second species identified is P. umzambense Schultze-Motel. These woods are compared with other west coast woods, both onshore and offshore, and the Upper Cretaceous coastal environment is postulated

From the womb into the world:Protecting the fetal brain from maternal stress during pregnancy

No other period in a child's life matches the speed of brain development than the first nine months in the womb. Rapid growth goes hand in hand with enormous potential, but also with great vulnerability. This policy-focused review focuses on maternal mental health as a key factor for fetal brain development. Already during pregnancy, the fetal brain wires differently when exposed to maternal stress, and children prenatally exposed to stress have a higher risk of developing neurodevelopmental disorders. Maternal prenatal stress is preventable, treatable, and tractable by policy. Research-based, policy recommends: (1) screening for maternal mental health issues throughout pregnancy, (2) encourage talking about prenatal mental health, (3) evidence-based interventions for pregnant women with mental health issues, (4) avoiding stress-inducing communication towards pregnant women, and (5) stimulating positive postnatal parenting. Investing in healthy pregnancies will improve fetal brain growth, and, ultimately lead to a healthier next generation

Do sunk exporting costs differ among markets? Evidence from Spanish manufacturing firms.

In this paper, we test the hypothesis of sunk exporting costs differing among markets. We use a sample of Spanish firms from Encuesta sobre Estrategias Empresariales (ESEE) for period 1991-2002. Our results confirm the importance of those sunk costs and demonstrate that they differ depending on the market they export to. Although most of the firms exports to developed markets, the costs to enter (and "to re-enter") are greater in those markets.Sunk costs, heterogeneity of firms, Regionalism.
